While the speaker cables, no matter how long and positioned, will not pick up noise that would be reproduced by the speaker. What could happen is that induced RF into the speaker cables could adversely affect your amplifiers and cause them to act badly. If they are no-feedback tube amps, less likely. If they use feedback, either tube or ss, you may have a problem there. You might try to isolate the pick-up location by starting with the amp(s) and removing the interconnects with only the amps on to see if you have the buzz. A shorted input may be good to try as well as an open input. If quiet, then work your way through the system with one component at a time. Good Luck!
David,
The tracer probe is showing 60Hz noise in the speaker cables even though the 300B amp is unplugged. what would that indicate?
Yes, I removed all power chords. Going to connect one amp at a time and see how it goes. Hopefully, I will replace the dimmers tomorrow.
